Hi,
I was trying to set a receive timeout on a socket, however when I use setsockopt function, it returns ENOPROTOOPT error. Please see below the snippet of my code. I am developing an application over nRF52840 DK, and I am using nRF Connect with ncs version 1..5. I would really appreciate your help in this regard.
Best regards,
Omer
bool init_app()
{
bool ret = true ;
recv_timeout.tv_sec = RECEIVE_TIMEOUT_IN_SECONDS ;
recv_timeout.tv_usec = 0 ;
memset(&tx_addr, 0, sizeof(tx_addr)) ;
tx_addr.sin6_family = AF_INET6 ;
tx_addr.sin6_port = htons(TRANSMITTER_PORT) ;
inet_pton(AF_INET6, CONFIG_NET_CONFIG_MY_IPV6_ADDR, &(tx_addr.sin6_addr)) ;
tx_sock_id = socket(AF_INET6, SOCK_DGRAM, IPPROTO_UDP) ;
if(tx_sock_id == SOCKET_ERROR_CODE)
{
printk("Error in creating socket for communication \n") ;
ret = false ;
}
if(setsockopt(tx_sock_id, SOL_SOCKET, SO_RCVTIMEO, (const char *) &recv_timeout, sizeof(recv_timeout)) < 0)
{
printk("Error in setting socket option \n") ;
switch(errno)
{
case EBADF:
printk("sock id is not a valid socket descriptor \n") ;
break ;
case EFAULT:
printk("Not a valid address is optval \n") ;
break ;
case EINVAL:
printk("oplen invalid \n") ;
break ;
case ENOPROTOOPT:
printk("Unknown option \n") ;
break ;
case ENOTSOCK:
printk("File not a socket \n") ;
break ;
default:
printk("Failure reason is unknown \n") ;
}
ret = false ;
}
}
